CHARLES C. HANSEN, OF EASTON, PENNSYLVANIA, ASSIGNOR T0 INGERSOLL-RAND COMPANY, OF NEW YORKrN. Y., A CORPORATION OF NEW JERSEY.

Roux-Drummer MACHINE.

Specification of Letters Patent.

.Patented May 19, 1914.

To all whom t may concern Be it known that I, CHARLES C. HANSEN, a citizen of Vthe United States, and resident of Easton, in the county of Northampton and State of Pennsylvania, have invented new and useful Improvements in Rock- Drilling Machines, of which the following is a specification. l

This invention consists in certain 1mprovements in rock drilling machines and comprises a suitable support, such, for instance, as. a wagon, amain frame carried thereby, anl auxiliary frame movable along the main frame intended to be lowered into engagement with the ground and a rock drill or other tool movable along the auxiliary frame toward and away from its work.

My invention further comprises a. machine Vof the above character in .which a turntable is provided for the main frame, the

auxiliary frame and the tool whereby the parts may be swung around into different positions with respect to the support.

The object of my invention is to provide a very simple and effective means for operating the different parts.

In the accompanying drawings, Figure 1 shows the rock drilling machine partially in side elevation and partially in section, Fig. 2 is a top plan view of the same, and Fig. 3 is a horizontal section showing some of the connections between the common engine and the several parts controlled thereby.

A suitable support is provided, which support, in the present instance, comprises a wagon having a frame 1, a platform 2 and traction wheels 3. A turntable 4 is mounted upon a track 5 carried by the wagon platform 2, an annular series of balls 6 being interposed between the turntable and track forming a roller bearing for the turntable. Means are provided for locking the turntable in its different rotary positions, which means comprises, in the present instance, three clamps 7. A main frame uprises from the turntable 4, the base members of which frame are denoted by 8, the upright side members by 9 and the diagonal braces by 10. 'I he side members 9 of this main frame are provided with vertical channels l1 for receiving longitudinally arranged upwardly bars 12 on the sides of an auxiliary frame 13 to permit the auxiliary frame to be moved upwardly and downwardly along the said main frame. The side members of this auxiliary frame .13 are provided with channels 14 for the reception of longitudinally arranged ribs 15 on the sides of the drill saddle 16 to permit the drill 17 to be moved and downwardly along the auxiliary frame. The rock drill 17 is operated 1n the usual manner by pressure fluid fed to the valve chest 17*, through the feed pipe 17 In the present instance, the'drill is fed by gravity to its work and the auxiliary frame is fed by gravity to its position" resting upon the surface ofthe ground being bored.

Means are provided for lifting the drill and for lifting the auxiliary frame as follows -A reversing hoisting engine 18 of 'any suitable type is mounted on the' wagon platform 2. The winding drum`l9 of this engine serves to wind and unwind a cable 20 leading under pulleys 21,22, 23, 24, carried by the wagon; from thence upwardly through the center of the turntable 4, around pulleys 25, 26, on the auxiliary frame 13, from thence downwardly around pulleys 27, 28, on the drill saddle 16 and from thence upwardly around a pulley 29 on the said auxiliary frame 13. A combined friction brake and'clutch 30 is provided for this winding drum 19. A second winding drum 31 is provided from which a cable 32 passes under pulleys 33, 34, on the wagon platform; thence upwardly through the center of the turntable 4 around a pulley 35 carried by the main frame; thence downwardly around a pulley 36 carried by a bracket 37 on the auxiliary frame 13. This cable then leads upwardly around a second pulley 38 on the main frame and from thence downwardly where it is secured to the bracket 37 of the auxiliary frame. A com bined brake and clutch 39 is provided for this winding drum 31. This engine 18 also serves as the driving means for propelling the wagon in either direction as follows One pair of traction wheels 3 is connected to the engine by providing gears 40, 41, sprockets 42, 43, chain 44; sprockets 45, 46 and chain 47. A manually operated clutch 48 is provided for connecting the sprocket wheel-16 to and releasing it from the gear e9 driven from the pinion 50 on the engine shaft 51. This engine 18 is also used for swinging the turntable i into 'its different positions as follows The turntable 1s provided around its periphery with teeth 52 which mesh with a pinion 53 carried by an uprightshaft 54, which shaft has a bevel brake operated gear connection 55, 56, with a longitudinally larranged horizontal shaft 57. This shaft 57 is provided with a bevel gear 58 and a cross shaft 59 is provided with a bevel gear 60 which mayy be thrown into and out of engagement'with the bevel gear 58 by means of a good lever 61. This shaft 59 is providedwith a chain and sprocket connection 62, 63, 64, with the engine shaft 51. It will thus be seen that a common means are provided for propelling a wagon, swinging the turntable and controlling the movements of the auxiliary frame and for controlling the movements of the rock drill.

In operation, after the engine has been manipulated to bring the wagon to the desired point for carrying out the drilling operation, the engine is disconnected from the traction wheels and is connected to the turntable for swinging the turntable to the desired position. The clamps 7 may then lock the turntable in position. The engine may then be connected to the auxiliary frame hoisting drum andthe clutch and to permit the auxiliary frame to drop down into position upon the ground in proximity to the hole to be bored. The engine may then be connected to the drill hoisting drum and the clutch and brake operatled to feed the drill downwardly to its wor When desired, the drill may be raised through the medium of the engme 18. The

auxiliary frame may also be raised by the operation of the engine and the turntable swung to a differentposition for boring another hole or the wagon may be moved to another position for starting a new drilling` operation.

While I have shown and described a rock drill as movable along the auxiliary frame, it is to be understood that any tool may be used without departing from the scope of my invention. It is also evident that various changes might be resorted to in the con struction, form and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the structure herein set forth, but

What I claim is 1. A wagon, a turn-table thereon, a main frame uprising from the turn-table, an auxiliary frame movable along the main frame, a rock drill movable along the auxiliary frame, -an-engine mounted on the wagon,
